On hobbyDB, data is received and recorded in three main ways...
Special users -- the Squad Members -- have hobbyDB superpowers that allow them to add items to the database. Items are added one at a time using a suite of tools available.
Over the years, we've received hundred-thousands of data donations in the form of books, CDs and CSV files. Squad members have added some of these database entries to the site and will continue to do so. If you like to donate Data or help with adding it to hobbyDB let us know!
Last, but certainly not least, we have the ability to upload database entries in mass using an onsite data uploader. We have uploaded dozens to ten-thousands items this way. You find some examples here and some more information on our uploader here.
